Abstract
Fungi are diverse organisms found in nearly every global environment as key components in nutrient cycling and decomposition. To date, most fungal diversity has been documented from terrestrial habitats leaving aquatic habitats rarely explored. Even less is known about fungi inhabiting freshwater lakes, particularly the benthic zone that may serve as an untapped resource for fungal biodiversity. This study aimed towards understanding the diversity of fungi in one of the largest freshwater systems on Earth, the North American Laurentian Great Lakes. This study employed both culture-dependent and culture-independent environmental sequencing methods resulting in ~425 taxa, with 6% sequence overlap between these two methods. Further analysis indicates that fungal communities in the Great Lakes differ across depths indicating potential fungal diversity ‘hotspots’. These results indicate that fungal communities do exist in the benthic region and should be examined using both culture-dependent and culture-independent methods for a more complete snapshot of fungal communities.
